An incline with angle 37.0° rests on a level floor. A crate starting at the bottom is sent sliding straight up the slope and it slides along the incline to a maximum vertical height of 2.42 meters above the floor. The coefficient of friction between the crate and the slope is 0.385. Assume g = 9.80 m/s2.
Calculate the starting speed you must give the crate at the bottom of the incline so that it will reach a maximum vertical height of 2.42 meters above the floor.

A 313-kg crate rests on a surface that is inclined above the horizontal at an angle of 17.0°. A horizontal force (magnitude = 414 N and parallel to the ground, not the incline) is required to start the crate moving down the incline. What is the coefficient of static friction between the crate and the incline?
A box of mass m that was sliding along the floor, hits an incline plane and slides up the inclined plane with angle theta at a velocity v0. Find an expression for the maximum height, h, above the floor that the box reaches. This expression should not depend on m or theta, but only on v0 and g.
A 2.00-kg-box, starting from rest, slides down a frictionless incline. The incline makes and angle of ? = 30? from the horizontal and is fixed to a table. The incline has a maximum height of h = 0.500 m above the table that is itself H = 2.00 m above the ground. (a) Find the accleration of the box during the sliding period. (b) What is the velocity of the box as it leaves the table. (c) What horizontal distance...
Part 1) A small block travels up a frictionless incline that is at an angle of 30.0°above the horizontal. The block has speed 4.26 m/s at the bottom of the incline. Assume g = 9.80 m/s2. How far up the incline (measured parallel to the surface of the incline) does the block travel before it starts to slide back down? Part 2) Complete the following exercises. (Assume g = 9.80 m/s2.) (a) A small block is released from rest at...
A 1,440-N crate is being pushed across a level floor at a constant speed by a force of 250 N at an angle of 20.0° below the horizontal;(a) What is the coefficient of kinetic friction between the crate and the floor?(b) If the 250-N force is instead pulling the block at an angle of 20.0° above the horizontal, as shown in the figure (b), what will be the acceleration of the crate? Assume that the coefficient of friction is the...
1. A solid is rolling without slipping down an incline. At the bottom of the incline there is a ramp that creates a "quarter-pipe". A quarter pipe is one quarter of a circle, when viewed from the side. The sphere is released from rest, 4 meters above the bottom of the incline. The sphere rolls without slipping down the incline and back up the quarter-pipe. Thesphere leaves trhe quarter-pipe 30 cm above the bottom of the incline and is launched...
A. A crate of mass 66.8 kg rests on a level surface, with a coefficient of kinetic friction 1.49. You push on the crate with an applied force of 1,178. What is the magnitude of the crate's acceleration as it slides? Part A answer: 3.0327 m/s^2 B. Take the same crate of mass 66.8 kg and the same coefficient of kinetic friction 1.49, but now place the crate on an inclined surface, slanted at some angle above the horizontal. Now...
3. Starting from rest, a 5.20-kg block slides 1.60 m down a rough 30.0° incline. The coefficient of kinetic friction between the block and the incline is μk = 0.436. (a) Determine the work done by the force of gravity. J (b) Determine the work done by the friction force between block and incline. J (c) Determine the work done by the normal force. J (d) Qualitatively, how would the answers change if a shorter ramp at a steeper angle...
You are a member of an alpine rescue team and must get a box of supplies, with mass 2.10 kg , up an incline of constant slope angle 30.0 ∘ so that it reaches a stranded skier who is a vertical distance 2.80 m above the bottom of the incline. There is some friction present; the kinetic coefficient of friction is 6.00×10−2. Since you can't walk up the incline, you give the box a push that gives it an initial...
Use the work-energy theorem to calculate the minimum speed v that you must give the box at the bottom of the incline so that it will reach the skier. Constants Part A You are a member of an alpine rescue team and must get a box of supplies, with mass 2.00 kg, up an incline of constant slope angle 30.0 ° so that it reaches a stranded skier who is a vertical distance 2.50 m above the bottom of the...
